Sorrentino's company sued the clothing company in 2011 over its shirt containing the phrase "The Fitchuation." Sorrentino claimed that amounted to trademark infringement and other violations of his nickname, which is based on his abdominal muscles.

But U.S. Magistrate Judge John O'Sullivan recently ruled for Abercrombie and tossed the case. O'Sullivan concluded that the company marketed the shirt as a parody and that Sorrentino's company didn't start selling its own shirt until later. And the judge found the products are not the same and thus can't confuse consumers.

"Jersey Shore" ran on MTV for six seasons, ending last December.
